Abstract
Two myomas; one of them is subserosa and intramural in the right fundus measuring 8 cm and the other one is intramural in the posterior wall of the uterus measuring approximately 6 cm determined in the ultrasound examination of a 36 year old woman who is gravida 1, para 0, has 37-38 weeks pregnancy according to her last menstrual period. On 11th day after cesarean section the patient who came back with fever, infected vaginal flow and abdominal pain had an another operation because of being sepsis. At the operation we observed occurance of dehiscence at uterine’s old cesarean scar and that with omentum, small bowels which were sticking to that place created blastrone unprocessed bulk.So hysterectomy and left salpingectomy were made to the patient. Intramural big myomas at uterus may block emergence of effective contractions at uterus in the postpartum period. As a result in the early period, while postpartum hemorrhage may be observed depend on uterine atony; in the late period it may cause to pyometra in consequence of lochia drainage disorder and occasionally to sepsis as happened in our case.
